The population dynamics of small and middle-sized pelagic fish are subject to considerable interannual interdecadal fluctuations in response fishing pressure natural factors. However, the impact environmental forcing on these stocks is not well documented. Moroccan Atlantic coast characterized by high variability due upwelling phenomenon, resulting a significant abundance variation catches spec...

Abstract This research describes a first approach to analyse the effects of using high-pressure processing (HPP) as pre-treatment before frozen storage and subsequent canning fish. For it, Atlantic Chub mackerel (Scomber colias) was subjected HPP (200, 400 600 MPa for 2 min) followed by freezing (−30 °C 48 h), (−18 °C 0, 3, 6, 10 or 15 months), canned (3 months at 20 °C). Lipid damage developme...

The phylogenetic or evolutionary relationships of species of Cypriniformes, as well as their classification, is in a era of flux. For the first time ever, the Order, and constituent Families are being examined for relationships within a phylogenetic context. Relevant findings as to sister-group relationships are largely being inferred from analyses of both mitochondrial and nuclear DNA sequence...

The effects of a 6 degrees C difference in water temperature on maximum sustained swimming speed, swimming energetics and swimming kinematics were measured in the chub mackerel Scomber japonicus (Teleostei: Scombridae), a primarily coastal, pelagic predator that inhabits subtropical and temperate transition waters of the Atlantic, Pacific and Indian Oceans. New data for chub mackerel acclimated...
